php对数字进行万、亿单位的转化

php对数字进行万。亿的转化

/**
 * 格式化数字
 */
public function float_number($number){
    $length = strlen($number);  //数字长度
    if($length > 8){ //亿单位
        $str = substr_replace(strstr($number,substr($number,-7)," "),".",-1,0)."亿";
    }elseif($length >4){ //万单位
        //截取前俩为
        $str = substr_replace(strstr($number,substr($number,-3)," "),".",-1,0)."万";
    }else{
        return $number;
    }
    return $str;
}

PHP 数字转为大写金额(面向对象版)

本人在网上找了很久都没个完整能用的，于是只好自己写个(有效位数整数部分至千万亿，小数部分至小数点后四位)

$time_start=getmicrotime();

function getmicrotime(){
list($usec, $sec) = explode(" ",microtime());

return ((float)$usec + (float)$sec);

}

/// CLASS BEGIN //

class Num2cny

{
/** 大写数字*/

private $cny_num = array("零","壹","贰","参","肆","伍","陆","柒","捌","玖");

/** 整数部分的单位*/

private $cny_int_unit = array("圆","拾","佰","仟","万","拾","佰","仟","亿","拾","佰","仟","万","拾","佰","仟");

/** 小数部分的单位*/

private $cny_dec_unit = array("角","分","厘","毫");

/** 大于1吗*/

private $greater_than_1 = FALSE;

/**

* 转为大写金额。

* @access public

* @param string

* @return string

*/

public function conversion($str) {
if(empty($str))
{
return "Please input a numeric value!";
}
if( ! is_numeric($str))
{
return "It is not a numeric value!";
}
$str = str_replace(",","",trim($str));// 过滤掉左右空格和逗号
$str = ltrim($str,"0");
$_integerStr = "";// 整数部分数字
$_decimalStr = "";// 小数部分数字
